You are right, Juki bought Nakajima and started producing the 180 280 series as their number DNU-241. Juki doesn't make the 241 any more. Both of those machines are copies of the Consew 206. If you find a manual for the Consew 206, that should help you. Here's a link for the 206 RB-5 which is a newer model of the 206, but it should still be very similar to the 180. CLICK HERE
No one lives forever, the trick is creating something that will.
